We show that certain events of the cell cycle can still occur in starfish oocytes or fertilized eggs from which the germinal vesicle (the prominent nucleus of prophase-arrested oocytes) has been removed before the induction of meiotic maturation. Two meiotic asters develop following hormonal induction of meiotic maturation in these enucleated oocytes. The asters then divide to form a transient tetrapolar figure. When enucleated oocytes are fertilized, the sperm centrosome duplicates at the… CONTINUE READING
